face=Arial><span style='font-size:10.0pt;font-family:Arial'>I talked to a guy
in the spring about his problems with a YS 140 Sport. He told me he had the
whole valve assembly drop into the cylinder. By the whole assembly I mean the
piece that is molded or pressed into the head. It looks like a cylinder with
the valve, the valve seat, the spring and retainer. He told me he had that
happened three times last year and he lost the whole season because of the
problem. I almost questioned what he was telling me because I had never heard
of it happening. Well this week end some one brought me an engine to repair for
him and the same thing had happened. My concern is if we buy a new head is the
same failure going to happen? Has there been a change in the heads for the non
DZ heads? Any comments would be appreciated.<o:p></o:p></span></font></p>
